TRC Beginner Programming Curriculum

Class 1

  • Introduction, overview: Everyone should bring a laptop to class. Student laptops are ok.
  • Set up [replit.com](https://replit.com/signup) accounts: Most students use their google account to sign in.
  • Create first java replit, Hello World
    • Click run and get output.
    • Discuss the basic components of a java program.
    • Explain the syntax.
    • Show a couple examples where the program breaks because of bad syntax. Explain the error messages.
  • Topics covered:
    • Variables
    • Primitive types and Expressions
    • Introduction to numeric types: int, long, float, double.
    • Numeric operators: +-*/%
    • Useful constants like Math.PI
    • Variable declarations and initialization
    • String types: simple string creation, concatenation
    • Introduction to boolean types and operators. && || == !=, >, < etc.
    • Some practice with these types- give a few simple programming problems

Class 2

  • Recap boolean expressions
  • Introduction to while loops
    • Using a variable to count loops
    • Simple programs using while()
      • Print the numbers 1 to 10
      • Print the numbers 10 to 1
    • Incrementing, decrementing,
  • Introduction to if/else statements
    • Simple conditional execution
    • Combine if with while. For example, print even numbers up to 20.
  • Introduction to Scanner and Random.
    • Ask the user to input their name and repeat it back
    • Ask for a number and repeat back its square

With these two we can start to build a complex program: play a guessing game: choose a random number between 1 and 10 and have the user guess the number, giving too low/ too high feedback. This might require step-by step building up the program with the students.

Assign the fizz buzz problem for homework.

    • Exercises: find the min, find the max, compute the average
  • Case statements
  • State machines
    • Soda vending machine
    • State transition diagram
    • What variables are needed,
    • Implementation as a class
  • Exceptions - throwing/handling
